STEVIE M. HOYE, OF BIRMINGHAM, CONNECTICUT, ASSIGNOR OF ONE-HALF 7 TOJOHN P. LEIN,

OF SAME PLACE.

MACHINE FQR CUTTING SHOE-SOLES.

SPECIFICATION forming part of Letters Patent No. 282,523, dated August'7, 1883.

Application filed June so, 1883. (No model.)

To on whom it may concern:

Be it known that I, STEVIE M. Horn, of Birmingham, in the county of NewHaven and State of Connecticut, have invented a certain new and ImprovedMachine for Cutting Shoe- Soles,&c.; andI do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming apart'of thisspecification, and to the figures and letters of reference markedthereon.

My invention has for its object to provide an improved machine forcutting shoe-soles or other similar articles out of leather, rubber, orsimilar material and it consists in certain novel details ofconstruction and combinations of parts, which I will first describe, andthen point out particularly in the claims at the end of thisspecification.

In the accompanying drawings, Figure l is a side elevation of a machineconstructed in accordance with my invention.

Fig. 2 is an end elevation of the same; Fig. 3, a cross-sectional viewtaken 011 the line a: of Fig. 1; Fig. 4, a longitudinal sectional viewtaken on the line 3 y, Fig. 2; Fig. 5, a cross-sectional view taken onthe line'y y of Fig. 1, looking up, showing the revolving head and thepattern-plate. Fig. 6 is a side view of one of the blocks sliding in thegrooves in the revolving head. I Fig. 7 is an end view of the same, andFig. 8 is a sectional view taken on the line a: as of Fig. 7.

Similar letters of reference in the several ures indicate the sameparts.

Arepresents the main frame of the machine,

which supports all of the operating parts.

B is the horizontal main di'ivingsliaft, supported in suitable bearings,b b, and having on its inner end a large cam, B, which operates atintervals to raise and lower atable, C, which slides in an uprightbearing in the main frame, and has its lower extremity extended down andpassed through a semicircular opening in the bottom of theframe, to.prevent the table from turning around in its bearings. This table C isfor the purpose of supporting the material to be cut. Between itsbearings the shaft B has keyed to it a bevel-gear wheel, B that mesheswith the corresponding gear, D, keyed o to anupright shaft, D, supportedin bearings d d, and having near its upper end a gearwheel, D thatmeshes with gear-teeth E on the revolving head E, carrying thecuttingknives; The revolving head E is formed with the broad circularbaseand the upwardly-extending tubular central part, having the annularflange, E, at its upper end, by which it is supported in the bearings inthe main frame. The under side of the head E is provided with twodovetailedgrooves crossing each other at right angles at the center, andin each of these grooves are two sliding blocks, F, on which are pivotedthe knife-carrying blocks F. The blocks F are provided at their outerends with a roller, f, the purpose of which will be hereinafterexplained. The pivoted blocks F are each provided near their outer endswith two small friction-rollers, f f, that are adapted to travel aroundthe inner side of the pattern-.

I plate J, and each of said blocks has also a small downward projectionwith dovetailed edges,

on which is adapted to be placed a triangular piece, G, carrying theknife-blade H. I This piece Gr is secured by a small screw, 71, passingthrough one of its sides and abutting against the projection. Theknife-blade H is fastened in the dovetailed groove in the inclined sideof the triangular piece by means of the wedge. shaped key I, which maybe secured by a small screw, as shown. The metal pattern-plate J isclamped at its ends in between the parts j j of the frame, and its innercircumference is formed to correspond to the shape of the sole to'becut, all as shown in Fig. 5.

K represents an arch-piece that extends over the top of the revolvinghead, as shown, and is fastened thereto by means of suitable bolts.Dependingfrom "near the center of this arch and passing into the hollowcenter of the revolving head E are two arnis, K K, that support attheirlower ends a square-shaped bearing-piece, through which a rod, L,supporting at its lower end the presser-foot L, isadapted to slide. Thisrod L is for a part of its length 9 5 made round, and projects through aperforation in the arch-plate; and it is-also encircledby a spiralspring, L", which bears against the extends between the smallfriction-roller on' the sliding block F and the outer end of the pivotedblock F, and tends to keep the slides at the outer ends of the grooves.

Situated between the upper end of the annular flange on the top of therevolving head and the under side ofthe arch-piece is a washer, N, forthe purpose of preventing any possible vertical motion of the head.

The operation of my machine is as follows: The shaft 13 is revolved inthe direction indicated by the arrow in Fig. 2, and, through the mediumof the bevel-gears B and D, shaft D, and gear D, revolves the headcarrying the cutting apparatus. At every revolution of the shaft B thecam B on its end, raises the table O, on which the leather or othermaterial to be operated upon is placed, to the position indicated bydotted lines in Fig. 1, against the pressure of the presser-rod, so thatthe presserfoot L is caused to bear down and hold the material firmly inplace while the headrevolves, and the small frictional rollers f f onthe ends of the pivoted block carrying the knife, .by reason of theelastic band tending to press them outward, follow the inequalities ofthe pattern plate, and the knives cut .a cone sponding piece out of thematerial 011 the table. Each time the table is raised by the cam thematerial upon the table is acted upon by the knives and a sole is cuttherefrom, while each time the table is lowered the operator shifts theleather or other material, so as to present another uncut surface to theaction of the knives.

Having thus described my invention, I claim as new 1. In a machine forcutting soles for boots and shoes, the combination of a revolving headhaving grooves in its lower face, slides worked in said grooves andcarrying cutting-knives, a pattern for guiding said knives, and meansfor revolving the head, substantially as described.

2. In a machine for cutting soles for boots and shoes, the combinationof a revolving'head carrying movable knives, means for rey'*olvi11g saidhead, a pattern for guiding said knives, a vertically-movable table uponwhich the material to be cut is placed, and means for moving the tableinto position, so that the knives are enabled to operate upon thematerial, substantially as described.

3. In a machine for cutting soles for. boots and shoes, the combination,with a revolving head carryingmovable knives, means for revolving thehead, and a pattern for guiding the knives, of a vertically-moving tableupon which the material is placed, means for moving said table in suchproximity to the knives as will allow them to operate upon the materialthereon, and a spring presser-foot adapted to hold the material whilebeing operated upon, substantially as described.

4. In a machine for cutting soles for boots and shoes, the revolvinghead provided with grooves extending transversely across its lower face,the movable blocks sliding in said grooves and carrying knives, and theelastic band for keeping the blocks in contact with a pattern, incombination with said pattern and means for revolving the head,substantially as described. 5. In a machine for cutting soles for bootsand shoes, the combination, with the revolving head having the tubularcentral portion, and provided with the grooves in its face, in

which move slides carrying knives, of the archpiece provided with thedownwardly-projecting arms supporting the square-shaped hearing, and therod carrying the presser-foot, and the spring encircling said rod,substantially as described.

6. In a machine for cutting soles for boots and shoes, the revolvinghead having the grooves in its lower face,"in combination withv theslides adapted to move in said grooves, the

blocks pivoted to said slides, having the friction-rollers on theirouter ends, the knife-carrier proper, and the knife secured thereto,substantially as described.

7. In a machine for cutting soles for boots and shoes, the combination,with the revolving head, and the slides having a radial movement thereinand carrying cutting-knives, of a pattern and means for holding theslides in yielding contact with the pattern, substantially as described.
